Specification of Letters Patent.

Patented May 2, 1916..

Application filed March 13, 1914. Serial No. 824,399.

To all whom it may concern Be it knownthat I, Go'r'rLIEB LEHNHERR,

a citizen of the United States, and a resident of Pittsville, in thecounty of Wood and State of Wisconsin, have invented an Improvement inStump Pulling and Handling Machines, of which the following is aspecification.

My present improvements relate particularly to a turntable constructionforming part of a stump pulling and handling machine of the nature to bepresently shown and described, my object being to provide a simple andpowerful arrangement for directing the boom of a derrick in a machine ofthe above nature, together with actuating means capable of impartingmovement to the turntable at a plurality of points thereof.

Certain other objects and the advantages arising therefrom will be madeto clearly appear in the course of the following description in whichreference is made to the accompanying drawings, forming. a part of thisspecification, and in which Figure 1 is a plan view, illustrating myimproved apparatus in connection with a traction engine of which latteronly certain general outlines are illustrated, the mast and swingingboom being removed. Fig. 2 is a side elevation of the parts shown inFig. l with the mast and boom in position, and Fig. 3 is a transversevertical sectiontaken through the apparatus substantially on line ell ofFig. 1.

My improvements are mounted and utilized in connection with a machine,the frame of which is generally indicated at A and is mounted uponwheels A, is to be drawn by a traction engine or the like, the frame ofwhich is generally indicated at B, suitable couplings connecting themachine which I have not shown as they may be any of the well knowntypes and their illus' trationwould serve no useful purpose.

I have shown only such parts of the traction engine by which my improvedmachine is transported from place to place and its component partsfurnished with the necessary motive power, as will serve to show themeans which I contemplate for utilizing the power of the tractionengine. I have therefore shown the fly wheel shaft .of the tractionengine at B (see Fig. 1), the fly Wheel 13 of which is preferablyprovided with a bevel gear 6 either attached to or forming a part of itshub, this gear being in mesh with a gear amounted upon a sleeve 0 inturn disposed loosely upon a driven shaft C which is rotatably supportedin suitable bearings connected to the traction engine, sleeve 0 beingadapted to be connected to shaft C by a suitable clutch including acontrolling handle C The rear end of shaft C has a rigid sleeve 0 thebore of which is squared to receive the similarly shaped end (2 of atumbling rod D, the opposite end of which is connected, by means of asubstantially universal joint at d, with the outer end of the maindriven shaft E mounted in bearings on the frame A ofmy improved machine.

Mounted on the main shaft E adjacent its outer end is a pinion e whichis controlled by a clutch e, of the internal expanding type and which isin mesh with a somewhat larger pinion f secured upon the outer end of aparallel shaft F, this latter shaft having a small pinion f secured uponits inner end and in mesh with a somewhat larger pinion g mounted uponthe rear end of a shaft G on which is secured the main drum G, this drumreceiving the rope (not shown) which is extended laterally from one sideof the frame of the machine and attached to the stump to be pulled fromthe ground, the gearing for driving this drum as thus described beingsuch as to develop sufficient power for the purpose.

The clutch e is moved forwardly to connect pinion c with shaft E and iscontrolled by a vertical projecting lever E as seen in Fig. 2 and may bemoved rearwardly to engage a bevel gear 6 also mounted on shaft E and inmesh with a similar bevel gear it secured upon one end of a shaft Hintermediately of which is loosely mounted the drum H upon which iswound the boom controlling cable I, a clutch connecting this drum H withits shaft H just mentioned. One end flange of the drum H is engaged by abrake band H by which movement of the drum is controlled when its clutchis released.

Mast I which is inclined slightly in a rearward direction and rises fromthe frame of the machine, is provided with a pulley i at its upper endover which the cable 1 passes, this cable being connected to the outerend of the boom J which is adjustable at its lower end to extend at adesired angle with respect to the machine and which may be moved to soadjust the same by the means to be hereinafter described.

At its relatively opposite end shaft H is )rovided with a sprocket wheelh connected y a depending sprocket chain is, to a lower worm shafthaving a worm in mesh With a worm Wheel 79 mounted upon the rear end ofa shaft K on which is secured the anchor drum K which receives one endof a rope or cable (not shown) to be extended laterally and secured to asuitable support and then drawn taut by winding upon drum K to I off-setthe strain of the machine in theopposite direction when a stump is beingpulled.

Mounted at spaced points adjacent the inner end of the main shaft E area pair of facing bevel gears e and 6*, between which operates a clutch 6also of the internal expanding type, the action of which is controlledby an upright lever E as seen in Fig. 2. Each of these bevel gears is inengagement with a somewhat larger bevel gear Z mounted upon one end of arelatively short transverse shaft L having a bevel gear Z at itsopposite end, gears e and e engaging-relatively opposite sides of saidgear L so that by throwing the clutch lever E forwardly, rotation iscommunicated to shaft L in one direction and by throwing the clutchlever rearwardly, gear 6 is engaged with the shaft E and rotation iscommunicated to shaft L in the relatively opposite direction. Gear Z atthe inner end of shaft L is in engagement with a similar bevel gear m atthe forward end of a shaft M mounted longitudinally above the main drumgear g,

this shaft having a sprocket wheel 'm/ at its rear end connected, bymeans of a vertically disposed sprocket chain a, to an enlarged sprocketwheel a mounted upon the forward end of the boom controlling shaft N.

The shaft N above mentioned is extended rearwardly and longitudinallyof'the frame A. and journaled beneaththe surface thereof to extenddiametrically across a turntable opening formed in the said frame, thisturntable opening having a stationary surrounding ring 0 forming abearing for a turntable'O all as best shown in Figs. 1 and 3. Thecontrolling shaft N is provided with an intermediate bevel gear nlocated within the turntable opening and in engagement with similargears 22 and 7) secured upon the inner ends-of relatively short shafts Pand P respectively, these latter shafts being journaled in the samehorizontal plane with the controlling shaft N and extending uponopposite sides thereof and at right angles thereto. The shaft N andshafts P and P are provided with small pinions and p in engagement witha circular rack 0 formed upon the lower surface of the turntable 0 sothat when rotation is communicated to shaft N in either directionthrough the connections above stated, the

several pinions 92. and 72 will be turned to move the turntable in acorresponding direction.

The lower end of the boom J is mounted in a casting J forming a footpiece and having laterally-projecting trunnions journaled in bearings 0extending upwardly from the turntable and by this means the boom may bereadily moved or swung either vertically or horizontally or both whenthe stumps are hitched by suitable connections to the boom end fortransportation from one portion of the field to another and suitablypiled for final disposition. Thus in the operation of my device andafter a stump has been pulled at'the side of the machine clutch lever Eis then manipulated to clutch either of the gear wheels 0 and c andpower is transmitted through the connections before described with theturntable to swing the stump around to a position in the rear of themachine. In such a position its weight will be balanced to a certainextent by the mechanism upon the frame of the machine most of which isplaced upon the forward portion thereof. The anchor rope is then thrownoff and the traction engine proceeds tothe point where the stumps are tobe collected drawing my improved machine with. the stump carriedthereby. Either gears e or e may then be clutched to swing the boom tothe desired side of the machine. The clutch 72, is then thrown off bymanipulating H and the stump lowered if it is so desired by permittingthe cable I to unwind under the control of the band brake H I claim:
